Author: Brian Rhodes, Published on Feb 07, 2019

Video intercoms are a growing market with video surveillance manufacturers expanding into this niche. IPVM is continuing its series of video intercoms tests, adding to our test of Zenitel/ Stentofon Turbine and Axis 2N.

Can Dahua become a viable low-cost alternative in video intercoms as they have done in IP cameras?
